The end of the earnings season is always a good time to take a step back and see who shined (and who not so much). Let’s take a look at how renewable energy stocks fared in Q2, starting with EnerSys (NYSE:ENS).

Renewable energy companies are buoyed by the secular trend of green energy that is upending traditional power generation. Those who innovate and evolve with this dynamic market can win share while those who continue to rely on legacy technologies can see diminishing demand, which includes headwinds from increasing regulation against “dirty” energy. Additionally, these companies are at the whim of economic cycles, as interest rates can impact the willingness to invest in renewable energy projects.

The 15 renewable energy stocks we track reported a mixed Q2. As a group, revenues missed analysts’ consensus estimates by 2.2% while next quarter’s revenue guidance was 9.3% below.

Inflation progressed towards the Fed's 2% goal recently, leading the Fed to reduce its policy rate by 50bps (half a percent or 0.5%) in September 2024. This is the first cut in four years. While CPI (inflation) readings have been supportive lately, employment measures have bordered on worrisome. The markets will be debating whether this rate cut's timing (and more potential ones in 2024 and 2025) is ideal for supporting the economy or a bit too late for a macro that has already cooled too much.

While some renewable energy stocks have fared somewhat better than others, they have collectively declined. On average, share prices are down 3.7% since the latest earnings results.
